The name of the debuff applied by a Horde Paladin's Seal of Corruption. The effect is considered a DoT and therefore cannot crit. It deals 30 damage every 3 seconds for 15 seconds(10 DPS), and can stack up to 5 times for 150 damage every 3 seconds totaling 750 damage for the full period. Melee strikes with the Seal active have a chance to refresh the 30 second timer, as well as add another stack. This is unlike some other seals, such as Seal of the Crusader, which have a chance to be refreshed by any melee strike made by the paladin regardless of seal (if any) active. This makes it possible to Judge Crusader, apply Corruption, and keep both debuffs active at the same time.
